Downloaded from www.Manualslib.com manuals search engine A CAUTION:
~~~~~ ~
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the’wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and
DEX-COOL (orange-colored,
silicate-free) antifreeze.
NOTICE:
If you use an improper coolant mix, your. engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered
by your
warranty. Too much water
in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the
system. These can be harmful.

The surge tank is located next to the engine block on the
passenger's side
of the engine.
The cooling system when hot is under a.lot of pressure.
If the
CHECK COOLANT LEVEL message appears on
the DIC, you will need to add coolant.
A CAUTION:
Tbrning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn
you badly.
Never turn the surge tank pressure cap
-- even a
little -- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the full cold mark, which is 2.5 inches (60 mm) below
the base
of the fill neck. Use a flashlight as necessary to
see into the tank.

When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear
an unusual noise. A fluid loss in this system
could indicate
a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level
on the dipstick.
The level should be
at the FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Maintenance Schedule booklet.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use.
If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.

c4; f **I- *.: C
We don’t make tires. Your new Cadillac comes with
high-quality tires made by
a leading tire manufacturer.
If you ever have questions about your tire warranty and
where
to obtain service, see your Cadillac Warranty
booklet for details.
A CAUTION:
Poorly maintained and improperly used tires are
dangerous.
Overloading your tires can cause
overheating
as a result of too much friction.
You could have an air-out and a serious
accident. See “Loading Your Vehicle” in
the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently
to maintain the recommended
pressure. Tire pressure should
be checked
when your tires are cold.
CAUTION: (Continued)
CAUTION: (Continued)
Overinflated tires are more likely to be
cut, punctured or broken
by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have
been damaged, replace them.
See “Inflation
-- Tire Pressure” in this section
for inflation pressure adjustment
for higher
speed driving.
Inflation -- Tire Pressure
The Tire-Loading Information label which is located on
the
rear edge of the driver’s door, shows the correct
inflation pressures for your tires when they’re cold.
“Cold” means your vehicle has been sitting for at least
three hours or driven no more than a mile.
If you’ll be driving at speeds higher than 100 mph
(160’km/h) where it is legal, raise the cold inflation
pressure of each tire to
35 psi (240 Wa). When you end
this very high-speed driving, reduce the cold inflation

pressures to those listed on the Tire-Loading
Information label.
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation
is all right. It’s not. If your tires
don’t have enough
air (underinflation), you can
get the following:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear.
0 Bad handling
Rough ride
0 Needless damage from road hazards. When to
Check
Check
your tires once a month or more.

tire. It should be at
60 psi (420 kPa).
How
to Check
Use a mod quality pocket-type gage to check tire
pressure. You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back
on the valve stems.
They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
( 10 000 to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See
“When It’s Time for New
Tires” and “Wheel Replacement” later
in this section for
more information.

Downloaded from www.Manualslib.com manuals search engine When It’s Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only 1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are
true:
0 You can see the indicators at three or more places
around the tire.
0 You can see cord or fabric showing through the
The tread or sidewall is cracked, cut or snagged deep

enough to show cord or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can’t be repaired well because
of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed on your vehicle when
it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When
you get new tires,
get ones
with that same TPC Spec number. That way
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle.
If your tires have an all-season tread
design, the TPC number will be followed by
an “MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial)
as your original tires.

Keep belts clean and dry.
I
I A CAUTION:
Do not bleach or dye safety belts. If you do, it may
severely weaken them. In a crash they might
not be
able to provide adequate protection. Clean safety
belts only
with mild soap and lukewarm water.
Glass
Glass should be cleaned often. GM Glass Cleaner (GM
Part No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films.
Don’t use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped
off later.
If abrasive cleaners are used on the inside of
the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
Cleaning the Outside of the
Windshield
and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running, wax
or other material may be on the blade
or windshield.
Clean the outside
of the windshield with GM
Windshield Cleaner, Bon-Ami Powder@ (GM Part
No. 105001 1). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with
a cloth
soaked in full-strength windshield washer solvent. Then
rinse the blade with water.
Wiper blades should
be checked on a regular basis and
replaced when
worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with
a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. (See “Recommended
Fluids and Lubricants” in the Maintenance Schedule
booklet.)

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your Cadillac
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical
to your Cadillac, see “Servicing
Your
Air Bag-Equipped Cadillac” in the Index.
Headlamp Wiring
The headlamp wiring has an individual fuse which is
powered by
a MaxiFuse@. An electrical overload will .
cause the lamps to go on and off, or in some cases to
remain
off. If this happens, have the headlamp wiring
checked right away.
MaxiFuse is
a registered trademark of Little
Fuse Incorporated.
Windshield Wiper Fuses
The windshield wiper motor is powered by a MaxiFuse.
If the motor overheats due to heavy snow, etc., the wipers
will stop until the motor cools. If the overload is caused
by some electrical problem, be sure to have it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load
is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or
goes away.

Downloaded from www.Manualslib.com manuals search engine Plan Ahead When Possible
Whenever possible, schedule an appointment for your
vehicle’s warranty work. Your Cadillac dealer can then
prepare
to meet your alternative transportation needs
and minimize inconveniences typically associated with
warranty repairs.
Owner Responsibilities
There are only two things which you will be responsible for
during the use of your courtesy vehicle.
You are required to
provide
insurance coverage and replenish the fuel used.
In many cases your own auto insurance policy may
provide primary coverage for the courtesy vehicle,
similar
to rental car agreements. Please, check with your
insurance company to be certain what’s covered.
This service is provided to you under the terms of the
New Vehicle
Warranty, therefore, it is imperative that your
vehicle be picked up fiom the dealership at the completion
of
the warranty service. Vehicles not picked up in a timely
fashion may incur rental
fees charged to the customer.
Some state insurance regulations make it impractical to
rent vehicles to people under
21 years of age. If you are
under
21 and have difficulty renting a vehicle, Cadillac
will reimburse
you, up to $30/day, for any documented
transportation you receive.
